Money-handling device

ABSTRACT

A paper money dispensing device stores bills in stacked relation, successively separates the lowermost bill from the stack of bills, and moves the separated bills to an area where they can be dispensed to a patron. That paper money dispensing device automatically senses when two bills stick together and are simultaneously separated from the stack of bills; and it moves those bills to a storage area for safe-keeping, and then separates further bills from the stack of bills and moves those further bills to the area where they can be dispensed to a patron. Where that paper money dispensing device is used to dispense a fixed number of bills, that paper money dispensing device separates the said number of bills from the stack of bills during each cycle of operation and then dispenses the separated bills at the start of the next-succeeding cycle of operation; thereby providing prompt dispensing of the bills to be dispensed during the next-succeeding cycle of operation. Where that paper money dispensing device is used to dispense variable number of bills, that paper money dispensing device separates the desired number of bills from the stack of bills and prompty dispenses the separated bills. That paper money dispensing device dispenses all of the bills of the desired number of bills at the same instant, and it folds those bills as they are dispensed; thereby minimizing the likelihood that a patron would inadvertently fail to take all of the bills due him.

This invention relates to improvements in Money- Handling Devices. More particularly, this invention relates to improvement in a paper money dispensing device.

' It is, therefore, an object of the present invention to provide an improved paper money dispensing device.

It would be desirable to provide a paper money dispensing device which stores bills in stacked relation, because bills occupy a minimum of space when they are in stacked relation. While it is desirable to hold bills in stacked relation with a paper money dispensing device, it is necessary to withdraw bills from the stack of bills one at a time. The paper money dispensing device provided by the present invention stores bills in stacked relation; but it withdraws those bills from the stack of bills one at a time and then moves those bills to an area where they can be dispensed to a patron. That paper money dispensing device automatically senses when two bills stick together and are simultaneously separated from the stack of bills; and it moves those bills to a storage area for safe-keeping, and then separates further bills from the stack of bills and moves those further bills to the area where they can be dispensed to a patron. In moving any bills, which stick together, to a storage area for safe keeping, the paper money dispensing device keeps those bills from being dispensed as a single bill and thus protects the operator of a vending machine, incorporating the paper money dispensing device, from loss due to the dispensing of two bills as one. In separating further bills from the stack of bills, the paper money dispensing device makes it possible to dispense the desired number of bills, even though some bills in the stack of bills stick together. It is, therefore, an object of the present invention to provide a paper money dispensing device which stores bills in stacked relation, which withdraws bills from the stack of bills one at a time, which automatically senses when two bills stick together and are simultaneously separated from the stack of bills, which moves those bills to a storage area for safe keeping, and which then separates further bills from the stack of bills and moves those further bills to the area where they can be dispensed to a patron.

It would be desirable to provide a paper money dispensing device which could dispense bills promptly during each cycle of operation thereof; and the present invention provides such a paper money dispensing de vice. Where the paper money dispensing device is used to dispense a fixed number of bills, that paper money dispensing device separates the said number of bills from the stack of bills during each cycle of operation and then dispenses the separated bills at the start of the It would be desirable to provide a paper money dispensing device which could dispense all of the bills of a desired number of bills at the same instant, and which could fold those bills as they were dispensed. The paper money dispensing device provided by the present invention separates each of the bills of a desired number of bills from the stack of bills and moves each of those bills to an area where they can be dispensed to a patron; and then it simultaneously dispenses all of those bills to the patron folding those bills as it does so. In simultaneously dispensing all of the bills of a desired number of bills, and in folding those bills as it does so, the paper money dispensing device provided by the present invention minimises the liklihood that a patron would inadvertently fail to take all of the bills due him. It is, therefore, an object of the present invention to provide a paper money dispensing device which separates each of the bills of a desired number of bills from the stack of bills and moves each of those bills to an area where they can be dispensed to a patron, and then simultaneously dispenses all of those bills to the patron folding those bills as it does so.

The numeral 154 denotes a pivot which is secured to the outer face of the guide 136, as shown by FIGS. 6 and 8. That pivot rotatably supports an L-shaped lever 156 which has an ear with an opening therein at the bottom of the vertically-directed arm thereof, and which has a roller 157 rotatably secured to the end of the horizontally-directed arm thereof by a pivot 155. A solenoid 158, which is referred to as the bill reject solenoid, is bolted to the'bottom 118 at a point disposed to the right of the guide 136, as that solenoid and guide are viewed in FIG. 6. The armature 160 of that solenoid is connected to the ear at the bottom of the verticallydirec'ted arm ofthe L-shaped lever 156 by a helical extension spring 162.

The numeral 166 denotes a horizontally-directed wall that is located in the lower right-hand portion of FIG. 6; and that wall extends between and is secured to the rear portions of the side walls 58 and 84. That horizontally-directed wall has a flange 168 which abuts the wall 84 and it has a flange 170 which abuts the wall 58, as shown by FIG. 3. An ear 172 extends upwardly from the rear edge of the horizontally-directed wall 166, adjacent the center of that edge; and an opening in that car accommodates a resilient stop 174, as shown by FIGS. 3 and 6. The front edge 176 of the horizontally-directed wall 166 inclines upwardly and to the left in FIG. 6; and it extends over the solenoid 158. A solenoid 178 is bolted to the upper surface of the horizontallydirected wall 166; and that solenoid is referred to as the bill feed solenoid. The armature 180 of the solenoid 178 can move'between a position where it abuts the core of that solenoid and the position shown by FIG. 6 where it abuts the resilient stop 174. A pin 181 connects the armature 180 with a link 182 which has the right-hand end thereof extending through a slot 192 in a connecting plate '188 that has the opposite ends thereof secured to crank arms 184 and 186, as shown by FIG. 3. The lower edge of the connecting plate 188 has a flange 190 thereon to stiffen that connecting plate. A pin 194 which is longer than the slot 192 is wide, is held within an opening in that portion of the link 182 which extends rearwardly through the slot 192. That pin will prevent accidental separation of the link 182 from the connecting plate 188, and it will respond to energization of the bill feed solenoid 178 to pull the lower end of the connecting plate 188 to the left in FIG. 6.

The crank arm 186 is rotatably mounted on the pivot 74, as shown by FIG. and the crank arm 186 is rotatably mounted on the pivot 104, as shown by FIG. 2. The pivots 74 and 104 are coaxial; and hence the crank arms 184 and 186 will rotate about the same axis. The connecting plate 188 and the crank arms 184 and. 186 constitute a rigid structure which is generally U-shaped in plan and which extends around the rear portions of the side walls 58 and 84. A bushing 196 is secured to the crank arm 184, as shown by FIG. 3; and a similar bushing 198 is secured to the crank arm 186, as shown by'FIG. 3. Those bushings are coaxial; and they rotatably support an elongated roller 200 which has a sleeve 202 thereon made from a material which has a high coefficient of friction. The roller 200 extends through the circular openings 65 and 116, respectively,in the walls 58 and 84; and those circular openings permit the crank arms l84.and 186 to move that roller, and the sleeve 202 thereon, in an arcuate path relative to the axis definedby the pivots 74 and 104. A sprocket wheel 204 is fixedly secured to that end of the roller 200 which projects outwardly from the bushing 196, and hence that sprocket wheel is adjacent the outer face of the wall 58, as shown by FIGS. 1 and 3. The weight of the roller 200 and the weight of the sprocket wheel 204 acts to bias the crank arm 184 and the connecting plate 188 for rotation in the clockwise direction in FIG. 5 and act to bias the crank arm 186 and the connecting plate 188 for rotation in the counter-clockwise direction in FIG. 2. Normally, the crank arm 186 and the connecting plate 188 will be in the solid-line position shown in FIG. 2; but they will respond to the pull, which the link 182 and the pin 194 apply to that connecting plate as the bill feed solenoid 178 is energized, to rotate to the dotted-line position shown by FIG. 2.

The numeral 206 denotes a horizontally-directed wall which serves as the floor of a currency receptacle 207 for stacked bills; and that wall is shown at the right of FIG. 6. The upper rear portions of the walls 58 and 84 define the sides of that currency receptacle, the partition 120 defines the front of that currency receptacle, and the flanges 64 and 92, respectively, on the rear edges of the walls 58 and 84 define the rear of that currency receptacle. The wall 206 has flanges 208 and 210 which abut the walls 84 and 58, respectively, as shown by FIG. 3. A slot, not shown, is provided in the wall 206; and that slot is parallel to the walls 58 and 84. The numeral 222 denotes an L-shaped bracket which has the horizontally-directed portion thereof secured to the under surface of the wall 206, as shown by FIG. 3; and a switch 224, that is referred to as the empty switch, is secured to the vertically-extending portion of that bracket. The actuator 226 of that switch extends upwardly through the slot in the horizontally-directed wall 206. Whenever a stack 228 of bills is disposed within the currency receptacle 207, the lowermost bill of that stack will hold the actuator 226 in its lower position; and, whenever that actuator is held in that position, the movable contact on the switch 224 will be in engagement with the left-hand fixed contact of that switch, as shown by FIG. 25. However, whenever all of the bills have been dispensed from the currency receptacle 207, the actuator 226 will move to the upper position indicated by FIGS. 3 and 6; and, at such time, the movable contact of the switch 224 will be in engagement with the right-hand fixed contact of that switch.

The numeral 230 denotes a flat plate which is shown in the right-hand portion of FIG. 6; and that plate is dimensioned to fit within the currency receptacle 207. That plate has a tab 231 at the rear edge thereof; and a notch 232 in one side of that tab accommodates the inner edge of the flange 64 while a notch 234 in the opposite side of that tab accommodates the inner edge of the flange 92. The notches 232 and 234 coact with the confronting edges of the flanges 64 and 92, respectively, to prevent accidental separation of the plate 230 from the currency receptacle 207 while permitting that plate-to move vertically relative to that currency receptacle. The plate 230 serves as a weight to urge the lowermost bill of the stack 228 of bills against the wall 206. A slot 236 is provided in the plate 230; and that slot is in register with the slot, not shown, in the horizontallydirected wall 206. Whenever the currency receptacle 207 is devoid of all currency, the actuator 226 of the switch 224 will extend upwardly through the slot 236 as well as through the corresponding slot in the wall 206.

The numeral 246 denotes a lever which is rotatably mounted on the pivot 72 in the upper left-hand portion of FIG. 5; and the lower end of that lever has an opening therein which receives one end of an elongated rod 250. A C-washer 252 seats in an annular groove in the end of the rod 250 to prevent accidental separation of that rod from the lever 246. The numeral 248 denotes a lever which is rotatably mounted on the pivot 102 in the upper right-hand portion of FIG. 2; and the lower end of that lever has an opening therein which receives the other end of the elongated rod 250. A nut 254 is threaded onto that other end of the rod 250 to prevent accidental separation of that rod from the lever 248. The rod 250 has an enlarged-diameter portion 256 ad- 'jacent the center thereof; and a sleeve 258 of a material which has a high coefficient of friction is telescoped over that enlarged-diameter portion. The sleeve 258 is in register with the sleeve 202 on the rotatably mounted, elongated roller 200; and, whenever the crank arm 186 is rotated from the solid-line position to the dotted-line position in FIG. 2, the sleeve 202 on the roller 200 will engage the sleeve 258. A' helical extension spring 260 has the upper end thereof hooked around the pin 70, and has the lower end thereof hookedin an opening in the upper end of the lever 246, as shown particularly by FIG. 5. A helical extension spring 262 has the upper end thereof hooked around the pin 100, and has the lower end thereof hooked in an opening in the upper end of the lever 248, as shown by FIG. 2. Those helical extension springs urge the ends of the elongated rod 250 downwardly toward the lower edges of the circular openings 81 and 114, in the walls 58 and 84, respectively. However, those springs can yield and permit that rod to be moved upwardly when the sleeve 202 on the roller 200 presses against the sleeve 258 on the enlarged central portion 256 of that rod.

The numeral 264 denotes an inclined guide which is suitably secured to the forward face of the partition 120, as shown particularly by FIG. 6. The central portion of the upper edge of that inclined guide is cutaway, as indicated by the numeral 265 in FIG. 6, to permit unimpeded upward movement of the sleeve 258 whenever that sleeve is engaged and moved upwardly by the sleeve 202 on the roller 200.

The torsion springs 328 and 330 urge the rollers 322 and 324 into engagement, respectively, with the knurled areas 280 and 282 on the roller 268. However, those springs can yield to permit the rollers 322 and 324 to be raised upwardly by bills passing between the confronting surfaces of those rollers and the knurled areas 280 and 282 on the roller 268. The inner diameter of the inner race of the ball bearing 326 is large enough to permit the rod 320 to move short distances relative to the slots 82 and 112, respectively, in the walls 58 and 84 without moving that ball bearing. Also, that ball bearing can move short distances, and thus can cause rotation of the lever 336, wihtout engaging the rod 320.

The upwardly-extending arm 340 of the lever 336 has an ear 342 thereon, as shown by FIG. 1; and that ear has threaded openings therein which receive the shanks of set screws 344 and 346. Lock nuts 345 are disposed at the forward face of the ear 342, and those lock nuts coact with the threaded openings in that ear to hold the set screws 344 and 346fixed relative to that ear. In practice, one end of an Allen wrench ispassed forwardly through the small, circular opening, which is in the partition 120 and which is shown by FIG. 3, to adjust the set screws 344 and 346; and then the lock nuts 345 are suitably tightened to hold those set screws relative to the ear 342. A pin 349 is secured to the partition 332, as indicated by FIG. 6; and a pin 351 is mounted on the upper arm 340 of the lever 336. A helical extension spring 353 has one end thereof hooked around the pin 349 and has the other end thereof hooked around the pin 351; and that helical extension spring biases the lever 336 for rotation in the counter clockwise direction in FIG. 6. However, that spring can yield to permit that lever to rotate in the clockwise direction when a bill is passed between the outer race of the ball bearing 326 and the adjacent surface of the roller 268.

The numeral 348 denotes a vertically-directed plate which is secured to the upper edge of the forward end of the partition 332 by screws, as shown by FIG. 6. The upper end of that plate supports a switch 350 and a switch 352; and the switch 350 is referred to as the double bill detection switch, while the switch 352 is referred to as the bill counting switch. A plate 355 of insulation is interposed between the plate 348 and one side of the switch 352; and the switch 350 abuts the other side of that switch, as shown by FIG. 1. A ferrule 357 of relatively-stiff plastic material is pressed or threaded onto the end of the shank of the set screw 346, and a similar ferrule 359 is pressed or threaded onto the end of the shank of the set screw 344. Those ferrules have plane faces which are larger than the end faces of the shanks of the set screws 346 and 344, and the plane faces of those ferrules are in register with the actuators of the switches 350 and 352. The switch 350 is normally held open by the set screw 346 and the ferrule 357; and the switch 352 is normally held open" by the set screw 344 and the ferrule 359. As shown particularly by FIG. 1, the actuator of the switch 350 is further in its retracted position than is the actuator of the switch 352; and hence the switch 352 will close before the switch 350 closes when the upper arm 340 of the lever 336 moves the set screws 344 and 346 away from the actuators of those switches. The set screws 344 will be set so the switch 352 will close whenever a single bill passes between the roller 268 and the outer race of the ball bearing 326; and the set screw 346 will be set so the switch 350 will remain open when a single bill passes between the roller 268 and the outer race of the ball bearing 326 but will close when two or more bills simultaneously pass between that roller and that outer race.
